Pineapple Caipirinhawith Sweet Lime Espuma

This cocktail is a zesty, airy confection that deftly uses contrasting textures—foam and firmness—to highlight how well lime, pineapple, and the sugarcane brandy cachaça play together.

Half of an organic lime, cut into 4 pieces

Four 1/2-inch cubes organic pineapple

4 organic sugar cubes

1 ounce freshly squeezed organic lime juice

1 ounce organic agave nectar

1 large organic egg white (see Note)

2 ounces cachaça

1 spiky organic pineapple leaf (optional)

In a cocktail shaker, muddle the lime, pineapple, and sugar cubes until the mixture has an even consistency. In a separate small shaker, combine the lime juice, agave nectar, and egg white to make the espuma. "Dry shake" (shake without ice) until the mixture is thickly frothy, about 30 seconds. Add ice cubes to the muddled mixture and pour in the cachaça. Shake vigorously, then pour the mixture, unstrained, into a tall glass. Top with the espuma and garnish with the pineapple leaf, if using.

Note: Make sure your egg whites are very fresh, and do not serve this drink to the elderly or anyone with a compromised immune system.
